get input value in react using hooks

import React, {useState} from 'react'

export default () => {
    const [fName, setfName] = useState('');
    const [lName, setlName] = useState('');
    const [phone, setPhone] = useState('');
    const [email, setEmail] = useState('');

const submitValue = () => {
    const frmdetails = {
        'First Name' : fName,
        'Last Name' : lName,
        'Phone' : phone,
        'Email' : email
    }
    console.log(frmdetails);
}

return(
    <>
    <hr/>
    <input type="text" placeholder="First Name" onChange={e => setfName(e.target.value)} />
    <input type="text" placeholder="Last Name" onChange={e => setlName(e.target.value)} />
    <input type="text" placeholder="Phone" onChange={e => setPhone(e.target.value)} />
    <input type="text" placeholder="Email" onChange={e => setEmail(e.target.value)} />
    <button onClick={submitValue}>Submit</button>
    </>
    )
}

Handle an input with React hooks

  const [inputValue, setInputValue] = React.useState("");

      const onChangeHandler = event => {
        setInputValue(event.target.value);
      };

      <input
        type="text"
        name="name"
        onChange={onChangeHandler}
        value={inputValue}
      />

Which React hook we use to get value from an input box?

import {useRef} from 'react';

const App = () => {
  const inputRef = useRef(null);

  function handleClick() {
    console.log(inputRef.current.value);
  }

  return (
    <div>
      <input
        ref={inputRef}
        type="text"
        id="message"
        name="message"
      />

      <button onClick={handleClick}>Log message</button>
    </div>
  );
};

export default App;
